Ahrefs' founder and CEO, Dmitry Gerasimenko, built his first document search engine when he was only 15. His interest in search engines never waned and in 2007, he revisited his work on search engines for documents and files. This led to the birth of our backlinks index in 2010, which in turn became the source of data for Ahrefs' first version of Site Explorer.
When launched, Site Explorer disrupted the stagnant field of backlink analysis and kick-started a new round of competition among SEO tool providers. It quickly became one of the world's best backlink analysis tools.
From our humble beginnings, Ahrefs has steadily grown. Today, we update our index with the freshest backlinks on the web every 15 minutes, and our crawler processes up to 8 billion pages a day. That's more than a third of what Googlebot does!
